STAPLE-FASTENER FOR WOODEN VESSELS.

SPECIFICATION forming part of Letters Patent No. 314,204, dated March 1 '7, 1885.

. Application filed July 18, 1884. (No model.)

To all whom it may concern/.-

Be'it known that I, WILLIAM 0. SWEET, a citizen of the United States, and a resident of Normal Park, in the county of Cook and State of Illinois, have invented new and useful Improvements in Staple-Fasteners for Wooden Vessels, of "which the following is a specification, reference being had to the accompanying drawings, illustrating the invention, in which Figure l is a perspective representation of one of my improved staplefasteners. Fig. 2 shows a section of wire out preparatory to being swaged and bent. Figs. 3 and 4 show the fasteners as applied to a tub for holding the cover thereon.

The present invention relates to a device for holding the covers on packages-sucl1 as wooden buttertubs and tobacco-pails, 8m. 7 The invention consists in a staple whose pointed shanks are projections from a plate which is made so thin at its middle portion as practically to be non-elastic, whereby the shanks. which are driven into the wood, will not be drawn out by the spring of the metal, and at the same time the thickness of the-connecting-plate shall not be such as to interfere when storing or handling fastened packages, or the shanks be removed by contact with other. articles.

A B B G C D D represent the fastener ready for use. D D are the shanks,which are made pointed at their ends, and of heavy metal at G G, where they are turned substantially at right anglesto the plate A B B.- Those portions of this plate at B Bare of thick metal, to form sufiicient heads for driving the shanks D D into wood. The middle portion, however,from B to A is formed gradually thinner, that it may be easily bent over the corner of a package, as shown at Fig. 2. The part A B B at its middle portion may be so thin as will leave only the tensile strength necessary to hold the cover E to the side F.

In the manufacture of these fasteners I prefer, as the best means now known, to make the devices of a continuous wire of the proper size and strength, and cut it in the required length diagonally, as shown at D, Fig. 4, as

the wire is passing on ordinary dies for that 0 purpose when the metal is hot,and by aswage, before the metal is cold, flatten the central part, A, at the same time bending the shanks D D. Dies and swages for doing analogous work are-so well known as to require no illus- 5 5 tration or further description. A fastener thus constructed will be about four times as wide at its middle part as at bases 0 O of the shanks, but, will not have so much metal in cross-section, for the reason that the said middle part will by the swagi ng process be stretched lengthw1se.

tion is attainedthat is, a fastener whose connecting-plate or bar contains less metal in 6 cross-section than the shanks at G O, or metal made so thin that where bent it has practically no spring to draw out the shanks D. In practice the thick parts B terminate so soon in the thin plate A that they will be so embedded in the wood, where the shanks are properly driven, that for ordinary packages the fastener will not project from the wood only about the thickness of ordinary sheet-tin.

and where the fastener is tinned or japanned 7 5 it gives a neat appearance, and does not discolor thewood. I claim that a staple-fastener with any form of reduced metal at the middle portion of the bar A would be my invention,

providing the spring of the metal was reduced so as not to draw on the shanks D D where applied to a package.

1 claim and desire to secure by Letters Patent A fastener for securing wooden package covers, formed of a single piece of metal,with tapered shanks D, and a thin metal plate, A, i which is thick enough at its junction with bases 0 of shanks D to form heads B for driving the shanks D in the wood, as specified.
